Trantorque Mini 12mm

The Trantorque Mini Series 12mm Keyless Bushing provides a high capacity, zero-backlash shaft/hub or coupling connection of mounted components to shafts measuring 12mm in diameter by means of a mounted mechanical interference fit and transmits up to 81 Nm of torque.

Best Suited For: Small shaft applications where speed and simplicity of installation and repositioning are critical.

Trantorque Mini Series 12mm Keyless Bushings provide a zero-backlash frictional connection that will never wear or pound out and can accommodate high-torque, thrust, bending, and/or radial loads. This product has exceptional concentricity and the ability to accommodate bending loads. The Trantorque Mini Series has limited axial movement during installation. All Trantorque units use a single hex nut for speed and simplicity of installation.

• All Trantorque units use a single hex nut for speed and simplicity of installation

All Fenner Drives keyless locking devices operate using the simple wedge principle. An axial force is applied- by either a hex nut (Trantorque) or a series of annular screws (B-LOC)- to engage circular steel rings with mating tapers. The resulting wedge action creates a radial force on the tapered rings, one of which contracts to squeeze the shaft while the other expands and presses into the component bore.
